CHARLES A. GARRETT, OF PHILADELPHIA, PENNSYLVANIA.
MACHINE FOR PRINTING AND FORMING CAPS FOR CONTAINERS.
Application filed June 4,
To all whom it may concern:
Be it known that I, GHARLEs A. GARRETT, acitizen of the United States residing at Philadelphia, in the county of hiladelphia and State of Pennsylvania, have invented.
an Improved Machine for Printing and Forming Caps for Containers, of which the following is a specification.
My invention is designed especially for providing printed caps for receptacles by feeding sheets or sheeted strips of suitable material, generally paper, through a punt ing mechanism by which impressions are printed at regular intervals, and insequence therewith through a forming mechamsm by which the printed sections are successively died out and pressed to shape, mechanism being provided for perforating the sections that are to he died out and pressed to shape when perforated caps are desired, as for boxes containing powder which it is desired to sift therefrom.
In the accompanying drawings, Figure 1 is a broken front elevation of a machine embodying my improvements; Fig. 2 is a side elevation of the same; Fig. 3 is a broken lan view taken on the line 3 3 of Fig. 1; ig. 4 is a sectional view taken on the line 4.-*-4PF of Fig. 3; and Fig. 5 is a sectional view taken on the line 5 --5 of Fig. 3.
In the form of the invention illustrated in the drawings, a frame 1 is provided with a vertical guide 2 for a die block 3 which is reciprocated in the guide by the crank shaft 1. through the connecting rods 5, the shaft being driven by a belt wheel 6. The block 3 is provided with a cutting die 7 and a male forming die 8, disposed concentrically with the die 7, the die 8 being movable relatively to the die 7 by the pitman 9 connected with the crank shaft l. The hollow base 10 is provided with the female die 11 disposed concentrically with relation to the dies 7 and 8 and with which said dies coact to out and form sheet material fed over thedie 11 beneath the stripper 12, which is secured thereto to prevent the rise of the sheet with the dies after the cutting and forming operations have been completed, the caps thus formed being delivered to the chute 13 whence they are discharged from the machine. This construction is of known character.
In accordance with my invention, a sheet 1 1 of paper board is fed over a table 15 and straps 15 beneath a stationary platen 16 Specification of Letters Patent.

and between the guides 17 over the female die 11, intermittently by the friction strips 18 and 19 together with the blocks 20 to which they are fixed. The blocks 20 are reciprocated by a rocking cam link 21 connected thereto by the pin 22 and connected by a link 23 with the crank arm 24 on a shaft 25 journaled in the bearing 26. The shaft 25 1s rocked by an arm 27 fixed thereon and connected through the flexible coupling 28 with. a link 29 which is connected flexibly with a coupling or collar 30 in which is journaled a stud 31 on a block 32 adapted to be set by a screw in a radial guide 34 of an arm 35 fixed on the shaft 4. The coupling 28 is connected with the parts 27 and 29 respectively by the pins 36 and 37 disposed at right angles to each other and the part 29 is connected with the part 30 by the pin 38 at right angles to the stud 31, to provide the desired flexibility of movement for trans forming the rotary movement of the stud 31 to the rocking movement of the shaft 25 at right angles thereto. A-coiled spring 29 connects the parts 2 and 29, to draw the latter transversely and prevent lost motion in the connected parts.
A cross bar 39 having journals 40 adapted to rock in the bearings 41, is provided with i an inclined dog 42 held in engagement with the paper strip 14 between the friction strips 18 by a spring 43, which connects a projection 4d on the cross bar 39 with the station ary part or anchor 45, the dog being able to rock against the action of the spring to permit the paper to be drawn forward thereunder and being held by the spring in engagement with the paper to prevent the latter from being moved backward upon the retraction of the parts 18. 19 and 20.
The blocks 20 are provided with the plate 46 having thereon the downwardly extending projections 47 for engaging the paper, the plate being supported by the springs 48 for holding it normally in the elevated position or at the top of its guides 49 in the blocks 20.
hen the cam link 21 is operated to draw back the blocks 20 with the connected parts, i
the toe 21' of this link or lever is elevated and the plate 16 is held by the springs 48 in elevated position out of engagement with paper. But in the forward movement, the
link 21 is rocked on the pin 22 toward the vertical, and the toe 21 depresses the plate 46 so that the projections 47 engage the paper, which is carried forward therewith without possibility of slipping or lost motion. At the limit of the forward movement, the cam link or lever 21 is drawn back so as to disengage the plate 46, which now rises and is disengaged from the paper, the
latter being held in position by the dog 42 so that the paper is moved the desired distance and held in position with avoidance of objectionable movements.
A printing block or form 49 is carried by an arm 50 which is connected with an arm 51, the lever formed by these arms being fulcrumed on the bearing 52. The arm 51 is provided with a laterally projecting member 53 which is connected by a link 54 with a toggle link 55 having a slot 56 therein through which and the link 54 passes a bolt 57 adjustable along the slot to vary the throw of the toggle link. The link 55 is fulcrumed on a bearing 58 and is connected by a pin 59 with a link 60, the latter being connected by a bearing 61 with the block 62 adapted to reciprocate in the way 63. A bifurcated lever 64 is fulcrumed on the bearings 65 carried by the block 62 and bears at its rear on a spring 66 supported by the block. The lever 64 carries an inking roller 67 adapted to be moved, by the reciprocations of the block 62, alternately in contact with the printing form 49 and the ink roller 68 which revolves in the ink fountain 69, the spring 66 acting to press the roller 67 against the printing form 49 and the roller 68. It will be understood that the form 49 is held in the relation to the roller 68 shown in Fig.
4 as the roller 67 passes between the parts 49 and 68.
The arm 51 is rocked, to operate the parts 49 and 67 in synchronous relation, by the toggle link 70, connected by the pin 71 with the arm, and the toggle lever 72 connected by the pin 73 with the fixed bearing 74, the
parts and 72 being connected by a pin 75 with an adjustable head 76 on the connecting rod 77 having a head 78 thereon. An arm 79, fulcrurned on a bearing 80, is connected by a pin 81 with the head 78 and reciprocates the rod 77 to operate the links 7 0 and 72. The arm 79 is adapted to be rocked by an arm 82, which is fulcrumed on the bearing 80 and is provided with a bolt 83 movable in the guide 84 thereof into and out of engagement with the notch 85 of a disk 86 forming the hub of the arm 79. The bolt 83 is reciprocated by a lever 87 which is fulcrumed on a bearing 88 and provided with a slot 89 engaging a stud 90 on the bolt 83. The arm 82 is rocked by a rod 91 having the bearing 92 through which and the slot 93 in the arm passes a bolt 94 adjustable in the slot, the rod being connected with a strap or collar 95 on an eccentric 96 which is fixed to and revolved by the shaft 4.
A pulley 97 on the shaft 4 drives a belt 98 which passes therefrom over a pulley 99 driven thereby. The pulley 99 has iixed thereto a pulley 100 over which passes a crossed belt 101 to a pulley 102 driven thereby, the latter being fixed on a shaft 108 journaled in the bearing 104 and having fixed thereon a sprocket wheel 105. A chain 106, passing over and driven by the wheel 105, drives a sprocket wheel 107 on a shaft 108 which is jonrnaled in a vertically adjustable bearing 109. A spur wheel 110 fixed on the shaft 107 engages a spur wheel 111 fixed to the ink roller 68 which is revolved thereby in the fountain 69.
A lever 112 is rocked on a stationary fulcrum 113 by the engagement of the lever with a stud 114 passing through the slot 115 therein and fixed to the die block 3, the lover being connected by a pin 116 to a block 117 movable under control of the vertical guides 118, the block being provided with the pins 119 for puncturing sheet material as it stands thereunder between the guides 17 in its intermittent movement to the dies.
It will now be understood that in the op eration of the machine, the rotating crank shaft 4 operates the dies 7 and 8 through the described intermediate mechanism together with the feeding mechanism comprising the device 20 with the connected parts through the described intermediate mechanism, and the printing mechanism comprising the form 49 with its connected parts through the described intermediate mechanism, all in synchronous relation, so that the paper 14 is fed forward step by step between the printing members 16 and 49 and between the forming members 7-8 and 11. Successive sevtions of the sheet are printed between the steps of the feeding operation and the printed sections are died out and pressed to form be tween the steps of the feeding operation, the printed sections being perforated by the device 119 (when connected in operating relation) between the steps of the feeding opera tion as such sections pass from the printing tothe forming mechanism.
